  1. SOLAR COLLECTORS Collector types and their sizing

  2. Solar system sizing Annualsumsof globalirradianceon horizontal surfacein the CR[kWh/m2]

  3. Solar system sizing

  4. Solar system sizing Annual solar irradiance on variously oriented (horizontal axis) and variously inclined (vertical axis) planes in the Czech Republic [kWh/sqm]

  5. Solar system sizing

  6. Solar system sizing ABSORPTANCE OF VARIOUS COLLECTORSURFACES

  7. Solar system sizing

  8. Solar system sizing Collector surface sizing for DHW • Determining the heat needed Usual consumption of DHW = 50 liters per person per day Equation Q=m.c.(T2-T1), where T1 = 10°C T2 = 45°C The heat needed is 2 kWh/person.day

  9. Solar system sizing Collector surface sizing for DHW • The period when the heat need for DHW is fully covered by solar collectors Usually designed for April – August According to the chart of average gains in each month, the least energy is available in April – 4 kWh/m2.day

  10. Solar system sizing Collector surface sizing for DHW • Determining daily gains and a collector area With the average 50% efficiency of the system in this period (involves also source instability!!!), the daily gain is 2 kWh/m2.day which is exactly the daily heat needed for 1 person. => 1 person ~ 50 liters DHW ~ 1 m2 of collector
